Figure 8

(a) Schematic illustration of the test of UV-pumped devices at a luminance of 91 cd/m2. (b) Relative changes in luminous efficacy of spray-coated films in remote mode and gel directly coated onto LEDs (in the case of the spray-coated film, the initial luminous efficacy is 28.1 lm·W–1; in the case of the gel, it is 47.5 lm·W–1). (c) Fluorescence spectra and CRI of spray-coated film in remote mode at a distance of 2 cm from the UV-LED (365 nm). (d) Fluorescence spectra and CRI of white gel directly coated on a UV-LED (365 nm).
